       8. The coaxial cable connector according to  claim 6 , wherein the other fixing piece includes another side plate extending from the side of the receiving passageway of the male connector such that the other side plate is opened outward. 
     
     
       9. The coaxial cable connector according to  claim 8 , wherein the other fixing piece further includes another catching plate extending from an end of the other side plate toward another insertion hole formed through the side of the male connector such that the other catching plate is fixedly secured in the groove of the male terminal assembly. 
     
     
       10. The coaxial cable connector according to  claim 1 , wherein the male connector is provided with a coupling lever, the coupling lever includes the catching protrusion formed at a top thereof such that the catching protrusion is inserted into a catching groove formed in the female connector. 
     
     
       11. The coaxial cable connector according to  claim 10 , wherein the coupling lever is configured such that front and rear ends of the coupling lever are fixed to the male connector such that a middle of the coupling lever is elastically movable upward and downward. 
     
     
       12. The coaxial cable connector according to  claim 11 , wherein the coupling lever is positioned at a rear end of the coupling lever with a protrusion contacting a front end of the female connector to restrict an insertion depth of the male connector. 
     
     
       13. The coaxial cable connector according to  claim 12 , wherein the protrusion is configured to elastically move the coupling lever downward when the protrusion is pressed. 
     
     
       14. The coaxial cable connector according to  claim 1 , wherein the male and female terminal assemblies respectively include male and female insulation housings and male and female metal shells respectively connected to shielding nets of the coaxial cable and the other coaxial cable respectively. 
     
     
       15. The coaxial cable connector according to  claim 14 , wherein the male and female metal shells are configured to surround front ends of the respective male and female insulation housings, and the female metal shell surrounds the male metal shell to define a shielding space during coupling between the male and female terminal assemblies.
